In figure: 1, holder, 11, the first connecting plate, 12, the second connecting plate, 13, the 3rd connecting plate, 2, support member, 3, fixed guide, 4, movable guiding rail.
Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of universal chuck, comprises holder 1, and holder 1 is is vertically connected and composed mutually by the first connecting plate 11, the second connecting plate 12 and the 3rd connecting plate 13, and this holder 1 has three-dimensional.The vertical support member 2 being respectively provided with on the first connecting plate 11, the second connecting plate 12 and the 3rd connecting plate 13, each support member 2 can move freely on each self-corresponding plate, and shape and the structure of the support member 2 in the present invention can be formulated according to the structure of workpiece.
Further, on the first connecting plate 11, the second connecting plate 12 and the 3rd connecting plate 13, be respectively arranged with fixed guide 3, fixed guide 3 is provided with at least one movable guiding rail 4 that square crossing connects with it, and support member 2 is vertically set on movable guiding rail 4.
As the preferred embodiment of the present invention, the first connecting plate 11 is provided with a movable guiding rail 4 being connected with fixed guide 3 square crossings, fixed guide 3 can adopt the usual line rail (standard component) in this area with movable guiding rail 4, fixed guide 3 along continuous straight runs are arranged on the first connecting plate 11, and lock with screw.One slide block is set on fixed guide 3, movable guiding rail 4 is fixed on slide block, movable guiding rail 4 can be moved on fixed guide 3.Same, a slide block is also set on movable guiding rail 4, support member 2 is fixed on this slide block, support member 2 is moved on movable guiding rail 4 by slide block.With same method, on the second connecting plate 12, arrange on two movable guiding rail 4, the three connecting plates 13 that are connected with fixed guide 3 square crossings three movable guiding rails 4 that are connected with fixed guide 3 square crossings are set.Certainly,, if want the workpiece that clamping shape is more complicated, on the first connecting plate 11, the second connecting plate 12 and the 3rd connecting plate 13, multiple movable guiding rails 4 and multiple support member 2 can be set.
As shown in Figure 2, drive unit comprises servomotor, and the rotating shaft of servomotor is connected with gear, the gear tooth bar that has been connected with a joggle, and described tooth bar is fixedly connected with cylinder, and the cylinder arm of cylinder is fixedly connected with support member 2.Servomotor is by servo controller control, and servo controller can adopt PLC(Programmable Logic Controller) or single-chip microcomputer.
Universal chuck of the present invention in use, can be at the first connecting plate 11, on the second connecting plate 12 and the 3rd connecting plate 13, coordinate figure is set, according to the geometric data of workpiece, set up unlimited work piece configuration reference point by servo controller, be the coordinate figure of workpiece in three-dimensional, such as establish X1Y1 coordinate on the first connecting plate 11, if the home position of support member 2 is X10Y10, support member 2 need move to the position of X11Y11, the shift value of this directions X (being the shift value between X11 and X10) can be inputed to servo controller, servo controller is according to the rotating speed of this shift value control servomotor, the rotating shaft of servomotor drives the gear being arranged in rotating shaft to rotate, gear pinion rack, because tooth bar is fixedly connected with cylinder, the cylinder arm of cylinder is fixedly connected with support member 2, therefore, servomotor is in the time rotating, band carry-over bar moves at directions X, rack drives cylinder moves along fixed guide together with support member 2 on directions X, in the time that support member 2 moves to X11 position, promoting support member 2 by cylinder again moves in the Y direction along movable guiding rail 4, in the time that support member 2 moves to the position of Y11, can movable guiding rail 4 and support member 2 be fixed by screw or alignment pin.With same method, drive the support member 2 on the second connecting plate 12 and the 3rd connecting plate 13 to move, difference is, the second connecting plate 12 and the 3rd connecting plate 13 upper supporting pieces 2 are that shift value is the distance between adjacent two movable guiding rails 4 at directions X, or distance between movable guiding rail 4 and connecting plate edge.In the time that the support member 2 on three connecting plates moves to needed position, movable guiding rail 4 is fixed on fixed guide 3 with screw or alignment pin, support column is fixed on movable guiding rail 4 with screw or alignment pin, complete the clamping of workpiece.
Universal chuck of the present invention is simple in structure, easy to use, goes for different product or workpiece, has reduced manufacturing cost.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
